Application filed December 12, 1908. Serial No. 467,30?4

To alt w/om tt ma'jconccm: `Be it known thatl, FRED G. MAYER., a citi zenof the United. States, residing at Mystic,

inthe county otPenning-ton and State of 5E South Dakota, have invented new and use ful improvements in Cnn-Openers, of which the i'oflowingis :L speqilication.

This invention relates to can opening inae'hines andthe object of the invention is to )rovide a device of this character which may e yreadil)T adjusted to any size can, and which when positioned upon `the machine will be effectively retained thereon without the necessityv ol holc'ng the saine while the top or lidr is being removed.

With the above and other objects in view "which will be more apparent as the description rogresses the invention resides in the 1 claimed.

' nove construction and combination of ele ments hereinattei` fully described, ,und

In thel :iceompanying drawings there has been illustrated a 'simple and preferred einn bodinicnt of the invention, and Ain which:

Figure l is n side elevation ot" a niaiphiiie construct-cd in accordance with the present invention. Fig. 2 is a central vin-tical longit udinal sectional View ol the saine. Fig. 3 is an elevation y'upon the line W ol F l 3 looking jin the direction of the arrows.

" inthe drawings` the numeral l designates i an 11i-. tegrally formed ofl'set portion thorn which. extends vertically e standznld 5. This Specification of Letters Patent.

' extending Patented May standard 5 is refereblyrectangular in crosssection and las one, of 'its faces provided with inout teeth designated bythe numeral 6 end clearlgrr'illustratedl iii Figs. 1 `and 4 of the drawings.

The numeral 7 designates the slidable supporting arm of the machine. This arm 7 is provided with :rf/rectangular opening4 upon itsy enlarged or headed portion 9, land 'the opening .8 is adapted for the reception ofthe rectnn'gular standard 5. 'The head 0 is provided upon one ol' its `leccs with outstanding ears 10, suitably 'sprl-ced apart and adapted for the reception oi a. pivoted lever ll.v A'The spliced ears 'l0 are of a distance apart approximately equeiing' the width of the teeth 6 provided upon the standard 5,and that portion of the head 9 between the 'said ears is cut awny for e suitable distance so es to provide an opening communicating with the teeth of the standard 5.

lhe lever .l1 is provided 'with a headed portion 12 which has its face provided with "'outwardlyY projecting teeth i3, adapted to engage the teeth 6 when the lever is swung upon fits pivot. By reference to Fig. 4- of the drawings it will'be noted that the pivot 14 ol1 the lever ll is pivoted eccentr .iljv ol the head lf2, soV tlm-t when the lever is swung at an angle in'either direction the teeth 13 will. be brought out oicontact'with the teeth o', thereby allowiiw' the heed 9 to be moved upon the standard in either direction. i

The opposite end of the arin 7 is provided with n. tubular socket member l5 which is :nl-ep ted for the reception of a cylindrical rod 16 having its upper rextremity provided'with an ollset handle 17. Themeinber 16. 1s retnincd in position upon the tubular head l5 through the medium of a. suitable o'liset or collar 1S, andhas its lower ortion'extending af suitable distance below il ber. U

The numeral 19 designates the head of the machine. This head 1 9 comprises an. outer annuler ring 2O having a pluralitT of spnced arms or spokes 21l radiating to e. central hub This hub 22 is provided with a. suitable end the spindleand hub are secure y locked 1e tubular inem-V o )enin r 28 ada itedi'or the rece' tion of the 10o l l P portion of the rod ors nndle'l contour corresponding with and of a cutting element e p that the head C may be rotated 'swung upon` its pivot 14 causing the teeth 13 n dina is provided with vertically arranged spaced nient or knife.

'the walls provided by the bore 26. The head i from the teeth 6 of vthe standard 5. Thel head is raised a sullicieiit distance awayl l l together through'the medium of a pin 24 engaging alining openings in the wall oint 35 and the cutting element '33 within l the head of the can. The handle 17 is then l rotated and the top or ca'p removed from the can.

By providing an adjustable knife as described, it will be apparent that the device should be rotated in only one direction so the teeth 3 arranged upon the base 1 are `beveled in a direction op osite to that in of the hub and the spindle. l.One of the radi ating spokes ,designated byilthe numeral 25 is preferably' rectangular in cross section vand is provided with a longitudinal groove or opening terminating a suitable distance away from the connection of the hub with the spindle 16. This opening comprises a cylindrical upper portion or bore 26 having a reduced portion 27 coininuiiicatingwit the ,lower face of the spoke provided within the bore and establishing a communication with the bore from the lower face of the spoke. rEhe reduced opening 27 has both of its longitudinally extending walls arranged in a substantially vertical plane, and one of these walls is smooth while the opposite wall.

which the head is rotatet thus the teeth provide aneffective bearing upon the lower face of the can and'prevent movement thereof in any direction.

Thilo l have illustrated and described the preferred embodiment ofthe machine, as it now appears to me, that minor details of construction within thc scope of the invention may be resorted to if desired.

Having thus fully described the invention what is claimed as new is:

1. In a device for the purpose set forth, a circular base having its'entire upperface proided with a plurality of notches arran series, a rotary head vertically adjusta lc in relation to the said base, said head having a bore provided with notches, and a removable cutting member adapted to be positioned within the bore and to engage the notches'.

2. ln a machine for the purpose set forth,

teeth 28.

The numeral 29 indicates the cutting elerlhis knife 29 is provided with head iortioii 8O of a cross sectional size apequaling or slightly lesser than 30 is provided with a reduced downwardly extending portion Ri having a centrally ar- 'i ranged tooth and provided with a knife or 25;. The reduced portion 31 of a lesser thickness than the width b'etween the vertical walls of the opening 2T so l a cylindrical base provided with notched in the bore l teeth arranged in series, a vertical arm upon 26 to bring the tooth 32 into or out of enl the base havinginset teeth, ahead supportgagenient with the teeth 28. of the arm 25. in'g member slidably mounted upon the arm lfv this arrangement it will be noted that the l of the base, an eccentrically pivotcd toothed cutting member 29 may bepositioned at any lever upon the support, spaced rollers upon desired point along the arm 25 so as to prei the head, said hea P vide for the variouswidths oi cans to be l extending bore provided with teeth upon one open cd by the machine. Ylhe s indie 1o has l of its sides, and a cutting element having an its lower portion projecting be ow the head l enlarged head and an oset tooth adapted to 1Q reduced and pointed so as to provide a be slidably positioned within the'bore of 'the means for pivotally engaging the can while y head, substantially as and :for the purpose the cutting element 29 is operated., set forth.

Trunnioned between the radiating arnis 21 3. ln a machine and the arm 25 are the rollers 34. rThese rollers 84 are adapted to extend'below the undersurface of the head 19 and are adapted to provide a bearing for the head as it is ro tated around the can which is to be opened.

for the purpose set forth',
